; ADJUSTABLE LINER.

Application filed May 27, 1927.

The present invention contemplates the provision of an adjustable liner or sets of adjustable liners designed to reduce the number of solid liners heretofore required to take care of the capacity of a linotype machine. A particular feature of the invention resides in the means employed to lock the relative adjustable elements of the liner in adjusted position while permitting their ready rela tive displaceability.

In the drawings:

Figure 1 is a top plan view of one embodiment of an adjustable liner according to my invention.

Figure 2 is a section of Figure 1 on its longitudinal axis.

Figure 3 is a section on line 33 of Fig ure 1.

Figure at is a top plan view of another embodiment of my invention.

Figure 5 is a section on line 55 of Figure 4, and

Figure 6 shows, in top plan view, a set of my improved liners designed to fill the capacity of, for example, a 30-em-pica slug casting typesetting machine.

Referring to Figures 1 to 3, the liner therein illustrated comprises a member 10 having a longitudinal top groove 10, a tongue 11 slidable in the groove, and a head 12 secured to the outer end of the tongue. Since head 12 receives most of the wear in the use of the liner it is preferably made replaceable and to this end as shown in Figs. 1 and 2 is provided with a recess 28 into which the end of tongue 11 takes and is secured by means of screws 29. Member 10 has a head 13 which may be secured to the body of the mold in any suitable manner. One margin adjacent groove 10' is provided with twopoint graduations, and the base of the groove is provided with teeth 14 aligning with these graduations. The inner end of the tongue, as shown in Figure 2, is provided with teeth 15 projecting beyond its lower plane and designed to mate with teeth 14 of the groove. Thus, the end of the tongue may be brought into register with any of the marginal graduations to give two-point adjustments to head 12 As shown, the em-pica spaces are numbered from four to twenty five, and one half em spaces are also indicated. Thus, any adjustment from four ems to twenty five ma be made in two-point steps.

2 shown in Figure 3, groove 19 and Serial No. 194,784.

tongue 11 are rhomboidal in cross section, and the teeth 14 and 15 are of substantial depth at the obtuse angle, merging into their respective backing surfaces at the acute angle. lVhen it is desired to move tongue 11 relative to member 10, it is merely tilted transversely about its edge 11 until pyramidal teeth 11 and 15 are disengaged. whereupon the tongue will be free to slide in either direction. The graduations, it will be noted, are above edge 11. The mass of the tongue is such that when it is swung back and pressed into the groove by the cap portion of the mold, there will be a wedging action. This wedge fit in itself acts to lock the two elements together. The teeth act as precautionary locking means, but primarily they serve as registering means for'the tongue.

According to Figures 4: and 5, a member 20 is provided with a longitudinal slot 20 whereby arms 21 and 22 and a head 23 are formed. The inner edge of arm 21 is outwardly convexed, as indicated in Figure 5, and the inner edge of arm 22 is longitudinally undercut. A tongue 24, having a head 25, mates between arms 21 and 22 and the contiguous edges of it and arm 22 are provided with teeth 26 and 27 at two-point intervals, these teeth being indicative of the two point graduations marked on the opposite side of the tongue.

In this embodiment, head 25 of the tongue will. be secured to the mold base and the frame elemen t will be moved relative thereto. lVhen an adjustment is to be made, the frame 20 will be transversely tilted about its edge 20 until the teeth are disengaged, whereupon it may be readily moved in either direction. Here, as in the first embodiment, the mass of the tongue is such as to give a wedge fit when the mold cap is applied.

Beyond ease of manipulation and possibility of minute adjustments, the described liners have the advantage that the cooperating measuring edges of the elements need not be separated when making adjustments so that speed and accuracy are enhanced. Moreover, the locking teeth are always face to face, so that if the two elements are not exactly positioned, upon their adjustment, at the desired graduation, the exact adjustment will be secured when the two are pressed together.

The co action of the three gauges shown 1n .figiir'e .1 is the same as that steam in Figures 1 to 3. The three gauges are so related, however, as to fill the capacity of a thirty em-pica machine. Liner A is graduated to cast slugs from five to sixteen ems, by twopoint steps, liner B from sixteen to twenty two, and liner C from twenty two to twenty five, the length of the tongue and head C of liner C being live ems. Three liners, each with twice the capacity of the one below it, thus complete the equipment for one thickness. In a forty-two em machine, the liners, according to this system, would have variations of four, eight and sixteen ems, respect-ively.

The usual equipment contemplates ten thicknesses, so that thirty of my improved liners would constitute complete outfit.

Having thus described my invention, I claim: i

1. A liner comprising a guide element, and a tongue element, said elements having cooperating locking means released upon a trans verse tilting movement of one of the elements relative to the other to permit relative sliding movements of the elements.
